How Watermelon Helps with Diabetes

There is a healthy connection between watermelon and diabetes, and that's mainly because of so many nutrients present in this sweet fruit. Here's a bit more about why it makes sense to make watermelon a part of your diabetes diet.

Vitamin A is great for your eyes and helps maintain the health of your cells. It also has vitamin C that protects your body from infections.

This fat-free and cholesterol-free fruit also contains magnesium and potassium that help improve your blood circulation and protect you from cardiovascular diseases. A cup of diced watermelon contains 170mg of potassium, which reduces the effects of sodium on your blood pressure.

2. It Contains Lycopene

Watermelon and diabetes go well together mainly because watermelon is rich in lycopene, a potent antioxidant that protects you from circulatory disorders. It neutralizes free radicals that can damage cells in your body. Free radicals can also oxidize cholesterol, making it to cause blockage in your arteries. Lycopene eliminate these free radicals and protect you from coronary heart disease. It also plays a role in protecting diabetics from cancers, like colorectal cancer, colon cancer, lung cancer, and breast cancer. The presence of lycopene makes watermelon a great way to prevent cognitive decline and dementia. Diabetes can cause nerve damage that may result in cognitive decline, but lycopene really helps reduce the effects.

3. It Contains Potassium

The high potassium content makes watermelon one of the best fruits for proper kidney functioning. It helps flush toxic compounds out of kidneys, which in turn keeps your blood uric acid levels on the lower side. This prevents kidney damage. If you're diabetic, you should have 5-10 serving of fruits and veggies in your diet. You can opt for three servings of watermelon a day mainly because of its high water content. It's beneficial even if you consume it in the form of a juice.

4. It Contains Amino Acids

Several studies have confirmed that since watermelon contains loads of amino acid called L-citrulline, it plays a big role in preventing high blood pressure. L-citrulline helps build L-arginine, another amino acid responsible for maintaining proper artery function. Regular use of watermelon or watermelon extract will also keep from your hypertension becoming worse with time.

What About Other Sweet Fruits, Can I Eat Them?

After knowing the connection between watermelon and diabetes, you may be wondering if you could eat other sweet fruits as well. The truth is no fruit is bad for you if you don't overeat. As long as you pay attention to your serving size, you can enjoy almost all fruits. Actually, you should be more careful about the amount of carbohydrates you ingest into your body.

If a fruit has lower carbohydrate content, you can consume a larger portion of that fruit without affecting your blood sugar level. It means that eating half-medium banana, ¾ cup of cubed pineapple, half cup of cubed mango, and 1/3 cup of cubed sapodilla will have the same effects on your blood sugar levels because they all contain about 15g of carbohydrates. So, just check the carbohydrate content and you will be able to enjoy a variety of sweet fruits without having to worry too much about your blood sugar levels.
